Abstract : The friction of thin films of electroplate silver on 521000 steel in ultrahigh vacuum has been shown to be lower at all loads if the film has been subjected to a high normal force loading. The friction of molybdenite sliding in the presence of oxygen increases when the system is pressurized with nitrogen, but pressurization with nitrogen decreases friction when sliding occurs in the presence of amonia.
